Application filed March 20, 1903. Serial No. l l8,'792. (N model.)

To (tZZ whom, it may concern:

Be it known that 1, JOHN W. COLLIER, a citizen of the United States, residing at Riverside, in the county of Riverside, State of California, have invented and discovered a new and useful Improvement in Turners fol-Sheet- Music; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in devices for holding sheets of music and for turning the same, when desired, by the operator upon a piano orother musical instruments; and the objects of my improvement are, first, to provide a frame to be placed upon a musical instrument carrying pivoted arms provided with clamps secured thereto; second, to devise swinging arms with clamps for the sheets of music in order that the sheets may be readily removed therefrom and other sheets inserted within the clamps; third, to make pivoted arms with pinions on the ends thereof which mesh with spring-operating rackbars controlled by the operator upon the musical instrument, and, fourth, to construct a folding frame for holding and turning sheets of music that occupies little space when not in use. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a view in elevation of the frame of my improved sheet music holder and turner, the pivoted arms in place upon the frame, showing the sliding rack-bars, springs connected thereto, and a lever for operating the rack-bars. Fig. 2 is an edge view of a portion of one of the side pieces broken away, showing the hinge for connecting the two halves of one of the pieces of the frame and a latch for holding the two parts together when in an extended position. Fig. 3 is a perspective view of one of the sliding rack-bars, a portion of the casing in which the rack-bar slides broken away, a part of the frame and lover pivoted thereto for operating the rackbars, a part of one of the arms pivoted to the frame, carrying upon one end a pinion adapted to mesh with one of the sliding rack-bars, one of the triggers pivoted to the casing, and

means for operating one of the triggers. Fig. 4 shows detail views of the washers located between the pinion ends of the pivoted arms. Fig. 5 is a perspective view of the sliding sheet-keeper secured to the central piece of the frame, sheets of music shown in dotted lines partly broken away. Figs. 6 and 7 are detailed views of the parts of the sliding sheet-keeper illustrated upon Fig. 5 of the drawings. Fig. 8 is a viewin elevation of one of the pivoted arms removed from the frame with the spring-clamp and two stays secured thereto, the pinion end of the arm in section, and showing the pivot-rod and washer in place thereon in elevation; and Fig. 9 is a view in cross-section of one of the sliding rack-bars and of the casing in which the triggers are pivoted, illustrating one of the triggers, a portion of the operating-wire, and spring for forcing the trigger outward in elevation.

Similar reference numerals and letters refer to like parts throughout the several views.

The numeral 1 refers to the top portion of the frame, 2 represents the base portion thereof, 4 4: indicate the two side pieces of the frame, and 5 the central piece of the frame, all of which parts make up the rectangular frame A.

Each of the two side pieces 4 4 and the central piece 5 is divided about midway of its length into two parts, and each of said two parts is connected by a hinge 3, as shown upon Fig. 2 of the drawings, in order that the frame A may be whenever desired folded upon itself when not in use.

Near the upper ends of the side piece 4 4: I pivot latches 6 6, and upon the lower ends of the side pieces 4: at of the frame I secure keepers 7 7, by means of which the free ends of the latches when inserted thereunder retain the two parts of each of the two side pieces in line with each other.

I secure the pivot-pin 8 to the under side of the top portion 1 of the frame about midway its length, upon which pin I pivot the swinging arms, each of which is referred to by the numeral 9.

A spring-clamp 10 is made in two parts, which are riveted to each other and to each of the arms 9 near the outer or free end thereof. These two-part spring-clamps 1O retain the sheets of music between them and also afiord a quick removal of the sheets of music already used and a ready insertion of other sheets of music between their downward projection parts to be used.

Each of the clamps is made of two parallel strips ofspring-steel. One of said strips is riveted to the outside of one of the strips of springsteel forming the swinging arm 9 and the other parallel strip of the clamp is riveted to the outside of the other or companion strip of spring-steel of the swinging arm 9. Each of the upper ends of the strips forming the clamp is provided with an angular lip 10 10. Each of the said two-part swinging arms at its pivoted end has a pinion 11, made integral with the arms 9, which meshes with the teeth of one of the sliding rack-bars 12, each of which is forced to move through the registering slots l3 13 in each end of the casing 14, securely fastened to the under side of the top portion 1 of the frame A and projects downwardly therefrom.

Each of the rack-bars is referred to by the numeral 12. To one end of each of the said rack-bars is fastened one end of a coiled spring 15, and the opposite end of each of said springs is secured to the upper end of a lever 16, which is pivoted to one of the side pieces 4 4 of the frame A. The lower end of said lever when freed from the retaining-pin 17, secured to one of the side pieces 4 4 of the frame, permits all the coil-springs 15 to assume their normal tension, when all the swinging arms 9 can then be thrown to one side of the frame, and the sheets of music are inserted between the downward-extending ends of the two-part clamp 10. The free ends of said clamps are bent inward toward each other and have the edges thereof serrated to slightly pierce the surface of the sheets of music, and thereby securely hold them between the two clamping-jaws.

Each of the swinging arms 9 is constructed of two strips of spring-steel riveted together, and at the free end thereof and near the pivoted ends of each of the said arms between the said two steel strips I rivet two stays 18 18, which support each sheet of music held by the two-part clamps 10 when the swinging arms 9 are released and carried to the opposite side of the frame by the swinging arms, rack-bars, and springs attached thereto.

In the upper end of each of the triggers 20 is a perforation through which the triggerpivoting rod 22 passes. The said rod 22 also is inserted through perforations in each of the washers 24, which are illustrated upon Fig. 1 of the drawings. These washers 24, together with the long washers 25, retain each of the triggers in true vertical allinement with their respective slots 27 in the horizon tal flange 28 of the casing 14. A spring 55 is secured to the casing to force each of the triggers against the rack-bars 12.

Each of the triggers 20 has a front projecting portion 29, to the outer end of which the trigger-Wire 30 is secured at one end. The opposite end of each of said wire 30 is fastened to a pivoted key 32. Each of said keys (seven in number) is pivoted upon a keyrod 37, which is mounted at each end in supports 34 34. The washers 36 are strung upon said key-rod 37 in order to keep each of the keys in true vertical alinement with the triggerwires and triggers, to which one end of said wires are connected.

Upon the central piece 5 of the frame A, below the longitudinal center thereof, I secure the sliding spring-retained keeper 40 for pivoting the lower ends of the sheets of music 60. (Shown in dotted lines upon Figs. 5 and S of the drawings.) The said keeper 40 consists of a body portion 41, through which the central piece 5 of the frame is inserted, and it is retained at any desired height thereon by the two side springs 42 42, fas-' tened within the said body portion 41 and exert pressure upon the edges of the central piece 5 of the frame, thereby retaining the keeper 40 at any position upon the central piece 5 that may be desired. The curved wings 43 43 of the keeper are connected by the plate 44, which is provided with two perforations 46 46 therein, into which the ends of the bow 45 are inserted, passing thence into the body portion 41 of the keeper 40. Near each of the free ends of the bow 45 is a notch 48, into which spring-fastener 47, secured to the body portion 41 of the keeper, automatically adjusts itself when the bow 45 is inserted within the body portion of the keeper, and thereby securely holds the sheets of music 60 at their lower ends to the plate 44 of the keeper and permits the said sheets of music to turn upon the bow as a center when the upper portion of the sheets of music is carried from one side to the other of the frame A by the swinging arms and its clamp 10 and stays 18 18.

It will readily appear from the foregoing description when read in connection with the drawings hereto appended and made a part of the specification and claims what is the operation of my invention,and further description of the mannerof operating my improvement is deemed unnecessary.

It is obvious that many variations and changes in the details of construction and arrangement of my invention that would readily suggest themselves to persons skilled in the art may be made and still be within the spirit and scope of my invention.

I do not desire to confine this invention to the specific construction, combination, and arrangement of parts herein shown and described, and the right is reserved to make all changes in and modifications of the same as come within the spirit of this invention; but I do desire to secure as my invention all features of construction and equivalents thereof that come within the scope of my improvement,as herein shown and described,and illustrated upon the drawings appended hereto.
